Six-year-old, Zach Tahir, from Salford, is a victim of a rare condition, called Pica. This means he feels like eating inedible things like moss, wall plaster and stones.
Having gnawed at the walls of his previous bedroom, he has received a special gift of an inedible bedroom on his sixth birthday.
His mother Rachel noticed that her son's craving for inedible objects went to a special level when he began to chew blinds and plasterboard. 'We don't know what appeals to him about the objects around him but there's nothing we can do to stop him trying to chew through anything and everything,' she said.
Ms Horn said: 'His wardrobes and chest of drawers have been made with rounded edges and installed so he can't pull them over'.
The bedroom has cost the family quite a huge amount - Ģ36,000.
